    • Crystallographic orientation mapping of lizardite serpentinite by Raman spectroscopy 

      Tarling, Matthew S.; Demurtas, Matteo; Smith, Steven A.F.; Rooney, Jeremy S.; Negrini, Marianne; Viti, Cecilia; Petriglieri, Jasmine R.; Gordon, Keith C. (Journal article; Peer reviewed, 2022)
      The serpentine mineral lizardite displays strong Raman anisotropy in the OH-stretching region, resulting in significant wavenumber shifts (up to ca. 14.5 cm−1) that depend on the orientation of the impinging excitation ...

    • Frictional properties and microstructural evolution of dry and wet calcite-dolomite gouges 

      Demurtas, Matteo; Smith, Steven A.F.; Spagnuolo, Elena; Di Toro, Giulio (Journal article; Peer reviewed, 2021)
      Calcite and dolomite are the two most common minerals in carbonate-bearing faults and shear zones. Motivated by observations of exhumed seismogenic faults in the Italian Central Apennines, we used a rotary-shear apparatus ...
